Non-vibrating three-dimensional variable-frequency spraying mechanical hand

Abstract

The invention discloses a non-vibrating three-dimensional variable-frequency spraying mechanical hand, which belongs to the field of coating machine equipment. The mechanical hand comprises a base and a hollow upright post, wherein the upright post is vertically fixed on the base; a reciprocating assembly is sleeved on the upright post, and comprises a sliding fixing frame and a spraying gun fixing frame; the sliding fixing frame is sleeved on the upright post; the spraying gun fixing frame is fixedly connected to the front end of the sliding fixing frame; the upper end of the upright post is provided with an upper traction guide wheel; the lower part of the inside of the upright post is provided with a lower traction guide wheel; a traction chain is wound between the upper and lower traction guide wheels; the two ends of the traction chain are fixedly connected to the upper end and the lower end of the sliding fixing frame respectively; the base is provided with a motor; the output end of the motor is in transmission connection with the lower traction guide wheel; the traction chain is connected with a counterweight block; and the counterweight block is arranged inside the upright post. When the three-dimensional variable-frequency spraying mechanical hand moves and switches in a reciprocating way, no remarkable pause exists, switching is smooth, and the three-dimensional variable-frequency spraying mechanical hand does not vibrate during reciprocating motion and is very stable.

Description

technical field [0001] The invention belongs to the field of coating machine equipment. Background technique [0002] Three-dimensional frequency conversion spraying manipulators are widely used in industries, especially in the coating industry at present. At present, many manufacturers in the market are designing and manufacturing single-axis, two-axis, three-axis and multi-axis three-dimensional frequency conversion spraying manipulators. [0003] The single-axis three-dimensional frequency conversion spraying manipulator is the earliest and widely used one. It is generally used for automatic spraying on one side. If full-scale spraying is required, the method of rotating work is used. The key of this three-dimensional frequency conversion spraying manipulator lies in the structural coordination of the moving parts. It is difficult to completely eliminate the gap. At present, most of the vibration phenomenon occurs when switching between reciprocating motions. The running ...
